Pinguicula caerulea and P. lutea have essentially identical leaves, with each leaf averaging about 1-1.5 inches long and with strongly rolled in (curled) margins. Read more at Vascular Plants of North Carolina.

When an insect becomes stuck on a Buttersort leaf's sticky mucilage, the edge of the leaf slowly rolls over. When the insect is digested, the leaf edges unroll. Read more at the Botanical Society of America.
